You can see Kyle's latest progress in the video above. Compare that with his video below on tracking spheres and you'll quickly see how far he's come.

Mixed reality doesn't just involve putting digital objects in our environment—it needs to understand us and our movements as well. The HoloLens requires a shallow learning curve, thanks to only having two core interactions—air tap and bloom—but that simplicity is also one of its shortcomings. Moving naturally and having the headset understand those more human gestures will allow for a more realistic and immersive experience.

The HoloLens signals a major leap in the technological capabilities available to us today, but it'll take time to get right. With so many inspired developers finding ways to push mixed reality forward, complex motion capture will clearly be a part of it through the Kinect (and other tools as well).
